| Tcp1323Opts | Tcp1323Opts - TCP Large Window support ( Windows 98 and later ). Used when an application requests a Winsock socket to use buffer sizes greater than 64KB. In previous implementations the TCP window size was limited to 64KB, this limit is raised to 2**30 through the use of TCP large window support as defined in [RFC1323] and implemented in Winsock 2. Tcp1323Opts also controls Timestamps. |
